With 25 mini-size velocity-sensitive keys and Octave Up/Down buttons, you can expand the keyboard to the full melodic range and play bass lines, chords, and melodies. V Mini also features four assignable knobs for manipulating effect plugins and virtual instruments: open and close filters, adjust volume levels, activate effects, tweak parameters, and more. Four velocity-sensitive backlit pads allow you to launch clips or finger drum with exceptional response, and pitch, modulation, and sustain buttons expand the expressive capabilities of your performing.
